PORTABLE WALL.

SPECIFICATION forming part of Letters Patent N o. 669,041, datedFebruary 26, 1901.

Application filed May 11| 1900- To @ZZ whom, it Duty con/067%:

Be it known that I, HUGH B. COPELAND, a citizen of the United States ofAmerica, residing at Denver, in the county of Arapahoe and State ofColorado, have invented certain new and useful Improvements in PortableValls; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the figures of reference markedthereon, which form a part of this specification.

My invention relates to improvements in portable walls provided with aglass, tile, or other similar or ornamental facing.

The invention will now be described in detail, reference being made tothe accompanying drawings, in which is illustrated an embodimentthereof.

In the drawings, Figure 1 isaJ face View of a wall constructed inaccordance with my invention. Fig. 2 is a cross-section, and Fig. 3 avertical section, of the same. The section in Fig. 3 is taken throughFig. 1 on a zigzag line. Fig. 4 illustrates the body portion of the walllocated in the rear of or behind the facing. Fig. 5 is a detail Viewillustrating several forms of metal bars which may be employed in theconstruction of my improved wall. Fig. 6 is a detail view illustratingthe Washer. Fig. 7 is a fragmentary section shown on av larger scale.

Similar reference characters indicating corresponding parts in theseviews, let the numeral 5 designate the wall-facing, which, as shown inthe drawings, is composed of diamond-shaped sections of opalescent glassand circular' parts composed of the same material and located at theangles of the diamond sections. The shape of the sections, however, aswell as the ornamental design of the facing, is immaterial, since it isevident that an infinite variety of designs, both as regards the form ofthe sections as well as their arrangement in the wall, may be employed.The other elements of the wall, as shown in the drawings, consist ofmetal bars 6, a wire screen 7, and a stratum of cement 8.

The rear surface of the facing-sections is Serial No. 16,382. (Nomodel.)

preferably roughened by grinding or in any other suitable mannerpreparatory to use. They are then placed face down on a flat surface.The screen 7 is soldered or otherwise fastened to the bars` G. Thisstructure, composed of the parts 6 and 7, is then placed upon theroughened surface of the facing-sections with the screen down or incontact with the said sections. The cement is then poured upon thescreen and passes through its meshes to contact with the roughcnedsurface of the face-sections. The cement lls the spaces between the bars6 and is preferably used in sufficient quantities to cover the bars.(See Fig. 2.) These bars are preferably provided with elongated openings6, through which fastening devices, as screws 9, may be passed for thepurpose of securing the wall in place. The elongated openings areadvantageous where the wall is to occupy a vertical position, since ifthe floor settles the wall may be moved downward therewith, theelongation of the openings being in a vertical direction. For use onceilings or horizontal surfaces the elongated opening has no specialadvantage, and the bars may be provided with a circular opening 6C, asshown at the extreme left in Fig. 5. The manner of forming the openingsin the bars is immaterial so far as this specification is concerned, andtherefore need not be described in detail. The several forms illustratedwill be readily understood. After the cement hardens the wall is readyfor use. This wall may be secured directly to the studding or uprightposts 10 of the partition by the screws or other fastening devices. (SeeFig. 2.) In line with the openings in the reinforcing-bars 6 thefacing-sections should be left out during 'the formation of the wall,and the said openings should be lled with wooden plugs 15, which areremoved after the cement hardens. After the screws are inserted thesesections may be secured in place by the use of cement, thus entirelyconcealing'the screws. The edges of the wall may be covered by a moldingcomposed of glass strips or other suitable material, as shown at 12 and13. (See Figs. 1 and 3.) y

A washer 15a is preferably used in connection with each screw 10. (SeeFigs. Gand 7 IOO As the cement 8 is poured upon the screen 7 a limitedportion of it Will pass through the screen to engagement with the facing5. In Figs. 2 and 3 the scale is so small that no attempt has been madeto illustrate this thin layer of cement between the screen and thefacing. In Fig. 7, however, this feature is illustrated, the said thinlayer being designated by the reference character 8a, in which thewasher 15 is embedded. As shown in the drawings, the screw-head iscountersunk in the Washer, making a smooth surface for the facing.

Having thus described my invention, what 1. A portable Wall composed ofa sectional facing, an open-mesh backing applied to the reverse side ofsaid facing, cement applied to the screen of the facing, and fasteningdevices passed through the mesh backing and the cement into the supportfor the wall, the said fastening devices being concealed in front by thefacing.

2. A portable wall composed of a sectional facing, an open-mesh backing,apertured bars located in the rear of the backing, cement applied to thebacking and bars, and fastening devices passed through the openings inthe bars and extending rearwardly into the stationary support for thewall, the fastening devices being concealed by the facing.

3. A portable wall composed of a sectional facing, an open-mesh backing,apertured bars located in the rear of the backing and provided withvertically-elongated openings, cement applied to the backing and bars,and fastening devices passed through the elongated openings in the barsand extending into the support for the Wall.

4. A portable wall composed of a facing, an open-mesh backing, aperturedbars located in the rear of the backing, cement applied to the backingand bars, and fastening devices passed through the openings in the barsand extending rearwardly into the stationary support for the wall.

5. A portable wall composed of a facing, an open-mesh backing, barslocated in the rear of the facing, cement applied to the backing andbars, and fastening devices passed through the backing and extendinginto the stationary support for the wall.

In testimony whereof I affix my signature in presence of two witnesses.

HUGH B. COPELAND.
